# hope this helps num = int(input('Please enter the number whose factorial is required : ')) count = 1 fact = 1 while count <= num : fact = fact * count count += 1 print('The factorial of the given number is : + str(fact)')

you can use math.factorial() to calculate factorial easily here is my solution it will print the output exactly as you want (python 3) from math import factorial as f n=int(input("Enter the number to check Factorial : ")) x=list(map(str,list(range(1,n+1)))) print(n,"! = "," x ".join(x)," = ",f(n),sep="")

num = int(input('input an int: \n')) def fact(x): if x < 2: print("1 = ", end=" ") return 1 else: print('{} * '.format(x), end=' ') return x * fact(x - 1) print('{}! = '.format(num), end=' ') print(fact(num)) this works, but in backwards order. 5! = 5 * 4 * 3 * 2 * 1 = 120

it's good practice to to import full modules, instead of certain functions
